IGNITION DEVICE FOR EXPLOSION-ENGINES.

SPEGIFCATION forming part of Letters Patent No. 741,329, dated October13, 1903. Application filed February 15,1902. Serial No. 94,291. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, HENRI GUILLOU, a citizen of the Republic of France,residing at Paris, France, have invented certain new and usefulImprovements in or Relating to Ignition Devices for Explosion -'Engines,(for which I have made application for Letters Patent in Great Britainunder N0. 501, dated January 7, 1902; in France under No. 312,803,

dated July 18, 1901; in Germany, dated November 11, 1901; in Belgiumunder No. 127,863, dated January-9, 1902, and in Switzerland, datedJanuary 11, 1902,) of which the following is a specification.

The present invention relates to an improved construction ofincandescent-tube ignition device applicable for explosion engines ormotors. I

The construction comprises a clamping device and a thumb-screw whichfacilitate the securing in place and rapid removal of the ignition-tubefor cleaning and repairing purposes and to enable it to be replaced atonce without the aid of keys or tools, and also the arrangement of aclearance-chamber situated in the ignition-passage in order to regulatethe exact time of ignition.

In the accompanying drawings, Figures 1 and 2 represent front and sidevertical elevations of the device. Fig. 2 is a sectional view of theparts seen in Fig. 3. Fig. 3 is a horizontal section on the line 00 0cof Fig. 1. Fig. at shows the perforated ring which regulates theadmission of the air to the chimney of the ignition device. Fig. 5 is aperspective view showing the means of clamping the ignition device tothe gas-supply tube. Fig.

6 is a vertical central section of the device as shown in Fig. 1 in aplane parallel to the plane of the paper.

Like numeralsind'ic-ate like parts throughout the drawings.

According to this invention, the ignitiontube 1, of refractory material,is arranged transversely to and extending outward from the chimney 2 andis contained in a tube or protector 3, so as to be in contact with theflame of a Bunsen burner 4, arranged at the base of the chimney andsecured in position by means of a nut or in any other manner. Aperforated ring 5 regulates the admission to the burner of air whichenters the-chimney was to support combustion. A socket 6, provided witha mica window, is arranged on a level with the tube 1 in order to permitof the inspection of its state of incandescence. The Bunsen tube 1 is socurved as to allow of an intimate mixture of the air entering passagestherein with the gas passing through the tube. The interior of theincandescence tube 1 communicates with the explosionchamber of the motorby a passage 8 in a block or tube 9, provided with a collar or union 10,by which the apparatus is secured to the motor. The other end of thepassage 8 is closed by a screw-plug 11, which when removed allows thepassage to be inspected and cleaned. The passage 8 also communicates oris provided with an explosion-chamber 30. This chamber is closed by ascrew'plug 13, carrying a threaded rod 14, on which are secured a numberof disks or rings 15. This set of disks or rings is adapted to fill moreor less the interior of the explosion-chamber, so as to control in anabsolutely precise manner the point or time of the ignition of themixture by storing up a smaller or greater quantity of inert gas fromthe previous explosion, so as to cause the explosive mixture (drivenback by the piston during compression-stroke) to reach earlier or latertheincandescent portion of the ignition-tube 1. Thus the time ofignition is regulated by lessening or increasing the number of the disks15.

In order to rapidly attach or detach the ignition-tube, it is providedwith a seat or projection 16, which rests partly in a recess 17 in theignition tube casing and partly in a recess 18 in the block or tube 9,before referred to. An asbestos washer 19 is placed in the recess 17.The casing or block 2O,wliicl1 is integral with the chimney, is providedwith two projecting lugs 21 22, each of which has a grooved or lippedend, the outer end of the tube or block 9 being placed between the lugs.These lugs are then engaged and gripped by a cap or yoke 23 withinwardly-turned arms 24, which engage in the grooves in the lugs,

a thumb-screw 25 being provided to tighten the parts by turning thescrew 25, whereby the lugs are clamped and strongly held thereby,tightly clamping the whole together.

What I claim as my invention, and desire to secure by Letters Patent, is

said tube, a clamping-yoke engaging'the lugs, a tightening-screw in theyoke and bearing against the tube and an ignition-tube having a seat orprojection resting partly in a recess in the tube secured to the motorand partly in a recess in the chimney.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. v

HENRI GUILLOU.
